Electrode Patch with Cut Surfaces for Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable electrode patches are inconvenient to attach and detach, and the varying distance between current and voltage electrodes degrades repeatability, with the risk of electrodes being readily detached due to clamp weight or wire force.
Innovation Solution
An adhesive electrode patch with conductive electrodes on either side of a substrate, featuring cut surfaces that maintain contact even when lifted by force greater than the adhesive force, and an indicator for precise alignment, allowing simultaneous attachment and separation of electrodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate disposable patch-type current electrode and voltage electrode are used, then flexibility in attachment is improved, but convenience deteriorates due to needing to attach separately
Solution Approach 1:
The patent combines multiple electrodes (current electrodes and voltage electrodes) onto a single disposable patch-type substrate, allowing them to be attached simultaneously to the test subject. This merging approach maintains the flexibility of using separate electrodes while improving convenience by enabling one-time attachment of all electrodes together.
2Adaptability or versatility
If electrode positions are adjusted for different users, then adaptability is improved, but repeatability deteriorates due to varying distances between electrodes
Solution Approach 1:
The patent pre-marks specific attachment positions on the disposable electrode patch before use. These pre-marked positions guide users to attach electrodes at standardized locations, ensuring consistent distances between electrodes across different users and applications. This preliminary preparation maintains adaptability while significantly improving measurement repeatability.
3Reliability
If clamp weight and wire force are applied to electrode, then electrical connection is improved, but electrode detachment risk increases due to exceeding adhesive force
Solution Approach 1:
The patent divides the electrode structure into multiple independent adhesive contact portions along the electrode body. This segmentation distributes the mechanical stress from clamp weight and wire force across multiple adhesive bonds rather than concentrating it at a single point. The cut surfaces create additional contact areas that maintain adhesive engagement even when portions of the electrode are lifted, preventing complete detachment while maintaining electrical connection.

AI summary
An electrode patch is disclosed. The electrode patch includes a substrate of which one surface has an adhesive force and extending in a first direction, a conductive first electrode disposed on one side of the substrate, and a conductive second electrode disposed on another side of the substrate and configured to be electrically separated from the first electrode. The first electrode includes a cut surface extending from a first contact portion contacting a first clamp to an inside of the first electrode, and the second electrode includes a cut surface extending from a second contact portion contacting a second clamp to an inside of the second electrode.
